PRESS.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed January 29, 1900. Serial No. 3,100.

To all whom it may concern:

Be it known that I, GEORGE E. PANCOAST, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Presses, of which the following is a specification.

My inventionrelates to presses, and more especially to means for supplying liquid for use in presses, and particularly to means for supplying damping liquid in lithographic presses.

It has for its object to provide better and more efficient rfeans for supplying liquid to one or more fountains in a press, and especially for supplying damping liquid to the water fountaln or fountains of a lithographic press; and also to provide improved and more efficient means for maintaining a desired level of liquid in the fountain or fountains of a press.

It consists of the novel devices herein shown and described.

In'the drawing accompanying this specification and forming a part hereof, I have shown my invention as embodied in and applied to the damping mechanism of a multi-color lithographic printing press. It is evident, however, that my invention is not limited to use in such a press, as it may be em loyed with advantage, in at least some of its features, in any kind of a press or any kind of a machine having liquid distributing or liquid applying mechanism; nor is it limited to supplying dam ing liquid, as it may be used, if desired, or supplying ink to any kind of a press, or for supplying any liquid to the fountain or fountains of a press. In the drawing accompanying this specification, I have, however, shown my invention as applied, in its preferred form, to a multi-color lithographic press, and to supplying water or other suitable damping liquid for use in such a press, and I will now proceed to describe in detail the said embodiment of my invention, as shown in the drawing.

The drawing represents a side view of a multi-color lithographic press with my improvement, in its preferred form, applied thereto, all parts of the multi-color lithographic press, not necessary to be shown to make intelligible the application of my invention to the press, being omitted.

In the press shown in the drawings, 1 represents the frame-work of the press, and 2, 3, 4, 5, 6 and 7 represent a series of fountains for supplying damping liquid for application to printing cylinders or forms 8, 8 mounted in the press concentrically around an impression drum (not shown). The liquid fountains 2-7 inclusive form a series of liquid fountains, one for each printing form, arranged at different levels. In the form of my invention, shown in the drawings, these are supplied with water or other sultable damping liquid in a manner presently to be described. 9, 9 are the water fountain rollers arranged in the fountains 27 in the usual manner. Ductors 10 arranged and operating in the usual manner take the damping liquid from the water fountain roller and deliver it directly to rider 11 in the usual manner in all of the cases shown in the drawings, except the two .at the left hand side where the ductors instead of taking the dam )ing liquid directly from the water fountalns 9 take it from supplementary rollers 12, which rotate with and take the damping solution from the water fountain rollers 9. The supplementary rollers 12 are used in the two positions shown, simply for the sake of convenience, and do not in any way affect my present invention. Riders 11 deliver the damping solution to water applying rollers 13 in the usual manner.

In the best embodiment of the invention the means for supplying the liquid to the fountains are constructed to maintain the liquid at an intermediate level in the fountains so that the fountains can not overflow or become dry.

In the embodiment of my invention, shown in the drawing, my im roved means for furnishing a supply of llquid to the fountains of the press, and for maintaining the desired intermediate liquid level in each fountain consist of a series of liquid receptacles, one for each fountain, each receptacle arranged at the same level as its fountain, and a pipe connecting each receptacle with its fountain for maintaining the same liquid level in the fountain as in the receptacle. The receptacles referred to are, as shown,

ing 14, 15, 16, 17, 18 and 19 and correspond respectively with fountains 2, 3, 4, 5, 6 and 7. The 'p1pes connecting the different receptacles with their corresponding fountains are as follows: pipe 20 connecting receptacle 14 with fountain 2, pi e 21 connecting receptacle 15 with fountain 3, pipe 22 connecting receptacle 16 with fountain 1, pipe 23 connecting receptacle. 17 with fountain 5, pipe 24 connecting receptacle 18 with fountain 6 and pipe 25 connecting receptacle 19 with fountain 7. By means of these pipes the same liquid level is maintained in each fountain as in its corresponding receptacle.

The desired level in each fountain is maintained by supplying liquid thereto, preferably continuously, and by providin for an overflow for carrying any excess of the liquid away, preferably to a lower fountain. In the embodiment of my invention, shown in the drawing, the liquid is supplied to and the overflow carried away from the receptacles, although my invention is not limited to this form of embodiment, as it is evident that for some features of my invention the supply of the liquid. could be made directly to the fountain or fountains themselves and the overflow proceed directly from the fountain or fountains themselves instead of to or from the receptacle or receptacles, the important feature being that the devices are provided for supplying a liquid to the distributing mechanlsm in a press such devices being located at levels corresponding to levels of the respective distributing mechanism and each su plied with an excess of liquid and allowed to overflow, whereby a level may be maintained in the said devices at the desired level or head. In the form shown, I supply liquid continuously to the highest receptacle 16 by means of a pump 26,

which forces the liquid from a reservoir 27 through pipe 28, discharging it into the highest receptacle 16. The excess of liquid from this receptacle overflows through an overflow. pipe 29 into the next lower receptaole 15. The excess from this receptacle passes through overflow pipe 30 to the next lowerreceptacle 17, and so on to the lower receptacles through the overflow pipe 31leading to receptacle 18, overflow pipe 32 leading to receptacle 14, :and overflow pipe 33 leading to the lowest receptacle 19. From this lowest receptacle an overflow pipe 34 discharges the excess back into reservoir 27. By reason of the fact that the several over- .flow ipes communicate with the receptacles at points below the tops of the receptacles and below the tops of the correspondingfountains the liquid is maintained substantially at a predetermined intermediate level both in the receptacles and in the fountains. By these means, the desired liquid level can be mainby Letters Patent, is:

the drawing, may, of course, be employed for supplying liquid to the' highestreceptacle or fountain, or to any one of the receptacles or fountains. 26 form no part of the invention, they are not shown in full, and will not be further described.

In the form of press, shown in the drawing, the inking mechanism is omitted for the sake of clearness. If desired, my improved device could be used for supplying ink to the ink fountain or fountains of a press or for supplying any liquid to a fountain or fountalns in a press. It is of especial value, however, in connection with supplying water fountains of a lithographic press, and especially of a multi-color lithographic press.

By means of my improvement, the liquid in the fountains can always be maintained at a desired level. This is of great value, especially in the damping or inking mechanismo a press, as thereby the amount of damping liquid or of ink. applied to the printing forms does not vary, but is the same at all times. My device is of especial value in multi-color presses where the damping or "inkin mechanism is generally not easily accessi 1e, and where supervision of cover at once any irregularity in the supply of liquid.

Many changes from the form of devices,

shown in the drawing, may, of course, be made without departing from my invention. What I claim as new and desire to secure 1.
